CENTRIFUGAL ATOMISER WITH FLOWS SWIRLED IN OPPOSITE DIRECTIONS Russian patent published in 2013 - IPC B05B1/34 B05B1/26 F23D11/04 

FIELD: process engineering.

SUBSTANCE: invention relates to fluid and solution sprayers. Proposed atomiser comprises housing with swirling chamber and nozzle. Housing is composed of union with fluid feed hole and coaxial cylindrical sleeve rigidly jointed thereto. Atomiser composed of centrifugal fluid swirler fitted to case lower part composed of cylindrical insert with, at least, three tangential inlet cylindrical holes. Note here that said sleeve makes a part of said nozzle and is arranged coaxially with second-stage centrifugal swirler. The latter has cylindrical part at its top section that changes into conical part to make annular conical clearance with housing. It makes swirler first stage composed of rod arranged coaxially there inside and provided with screw plate. Said rod is secured at three pins connected to conical chamber communicating first- and second-stage swirlers. Note that centrifugal swirler is fitted in the housing to make annular cylindrical chamber for feeding fluid to aforesaid tangential inlets. Swirler cylindrical chamber is communicated with nozzle outlet conical chamber.

EFFECT: higher efficiency of spraying.
